| 摘要: |
| 运用文献资料法、专家访谈法、录像观察法和数理统计法，以“非直即斜”为视角对世界优秀男子乒乓球运动员的变线特征、效果及其发展动态进行研究。认为：①非变线是运动员技战术运用的主要形式，变线是其辅助形式；变线和非变线在比赛制胜中发挥着几乎同等重要的作用，但变线的得分效果明显优于非变线。②逢直变斜和逢斜变斜是运动员的主要变线类型选择，在比赛中发挥着主导作用，而逢斜变直则发挥着战略上的牵制作用；三种变线类型间无明显得分效果差异。③以“非直即斜”为视角对变线形式进行分类能较为深入地揭示不同变线类型的作用和动态变化规律；各赛事中各类变线形式的运用情况和运用效果始终处于变化之中，变线调整以逢直变斜和逢斜变斜为主；进入新球阶段后，逢斜变斜类变线形式的得分效果有逐渐上升之势，逢直变斜的得分效果则表现出缓缓下降之势。以期为我国乒乓球队的科学训练和参赛提供参考 |

| Abstract: |
| Based on literature review, expert interview, video observation and mathematical statistics, the characteristics, effects and development trend of line changing of the world’s excellent men’s table tennis players from the perspective of “Either Line Drive or Cross Shot”. It is believed in this article: ①Nonchanging line is the main form of athlete’s tactics while changing line is its auxiliary form. Nonchanging line and changing line play almost equal role in winning, but the effect of changing line is obviously better than that of nonchanging line②Cross shot when meeting line drive and cross shot when meeting cross shot, the main changing types that athletes select, play a leading role in competitions, and line drive when meeting cross shot plays a strategic role to tie up; there is no scoring effect differences among those three types of changing line③The classification of changing line can reveal the function and the dynamic rules of the different types of changing lines from the perspective of “Either Line Drive or Cross Shot”. The use and application of various types of changing lines in all competitions are always changing but still dominated by cross shot when meeting line drive and cross shot when meeting cross shot. In the new stage of revised ball, the scoring effect of the category of cross shot when meeting cross shot is gradually increasing, while the scoring effect of cross shot when meeting line drive shows a trend of slowing down. This study serves as a reference for the scientific training and competition for Chinese table tennis team. |
